Trang 2Water has great importance for human life and all kinds of animals and plants Wherever there is water there is life and the Earth is the only place on the planet all countries But water is heavily contaminated with significant impact on the lives of every living thing on earth.
Trang 3• So we conducted
group learn about
water pollution issues may apply to this
situation rediscover
life with a source of
fresh water for the
earth
Trang 4I Concept
1 Environmental
“Environmental factors including natural
and man-made material factors closely related to each other, surrounded by people, affecting life, production and
survival, human development and
natural"
Trang 52 Environmental pollution
Environmental pollution is the state of the environment contaminated by
chemical, biological, radiation, noise,
affecting human health and other living
organisms Environmental pollution is
caused by humans and human
management
Trang 63 Pollution of the water environment.
Water pollution is a phenomenon waters such as rivers, lakes, sea, ground water is the human activity of
contaminating substances can cause harm
to humans and the creatures living in the wild
Trang 9• In large cities hundreds of industrial
production facilities are polluting the environment because there is no
water works and waste treatment
facilities.
Trang 10• For example, in the city of Taiyuan,
industrial waste water discharged from the base paper production, iron and steel,
non-ferrous metallurgy, coal mining in the dry season, the total volume of wastewater
in the region accounts for about 15% of
river flow Bridge, papermaking wastewater with a pH from 8.4 to 9 and 4 mg NH4 / 1, high levels of organic matter, brown
sewage smell unpleasant
Trang 11• Water pollution caused by industrial
production is very heavy.
and agricultural areas is also very serious
Trang 12• On the status of water pollution in rural
and agricultural areas, Vietnam now has
nearly 76% of the population live in rural
areas where infrastructure is backward,
the majority of waste human and cattle
should not be treated permeable ground or washed make pollution of surface water
and organic growing microorganisms
Trang 13• In agricultural
production due to
abuse drugs and
plant protection, the
water in rivers, lakes, canals contaminated greatly affect the
water environment
and people's health.
Trang 164 Due to population growth
3 Due to floods
Trang 176 Systems are not
dredged canals
leading to
accumulation of large amounts of organic
matter from sewage , garbage and causing siltation affect the
drainage of water
Trang 187 Landfill does not
meet the technical
Trang 198 The surface water
flow in rivers and
canals also
contaminated by oil from ship traffic ,
transportation or
other incidents on
the river , the sea
Trang 209 And many other causes also cause water pollution
Trang 21IV Sequel
Trang 23• Aaste from the
Trang 25• lack of clean water for the works
Trang 262 For economy
• Aquatic Livestock Retardation
Trang 27• The rice farmer becomes difficult
Trang 28• Health care costs due to pollution of water
is a lot
Trang 29V Solution
1 Prevent all sources far away from the
factory, work shaps, industrial park
2 Domestic wastewater from risidential
treatment area must pass before being discharged in to river
3 Carrying away impurities, plants and
animals residues from the down east
Trang 304 Trench systemsestablished in each city ecdogy house hold
5 Limited use of fertilizers and toxic
compounds in agriculture
